Evah Pirazzi double bass string, D Orchestra tuning.
Professional, synthetic core hybrid string. 2 gauges in Orchestra tuning.
Pros: Sound, ease of arco, great for pizz - does orchestral, jazz, everything. Very stable. These are really good strings
Cons: Nothing. Does not work with magnetic pick-up. If you take the tension right off (eg when adjusting sound post) too many times, the string will eventually give-up. Would be nice to have a 5th tuning set (with orchestral low C).
Other: Best strings I've played.
